Abstract: There is provided a vial cap with which, when there is a possibility that a cover which covers a stopper for a vial has come off and the stopper for the vial has been contaminated at a stage prior to use, the fact can easily be recognized. The vial cap is a resin vial cap (1) to be attached to a mouth portion (72) of a vial (70) to fix a stopper (74) fitted into the mouth portion (72) so that the stopper may not come off the mouth portion (72). The vial cap (1) is provided with a cap main body (8) that has an upper opening (6) formed therein and a cover (40) that covers the upper opening (6) of the cap main body (8). The cap main body (8) has a plurality of pin-receiving holes (10) formed therein, and the cover (40) has a plurality of fixing pins (46). Each pin-receiving hole (10) and a fixing pin (46) that is paired with the pin-receiving hole (10) are formed in complementary shapes.

Abstract: The present invention relates to a container-holding tray 1 for holding a plurality of bottomed cylindrical medical containers 50 side by side. The container-holding tray 1 includes the bottom surface part 2 and the container holding convex parts 4 formed on the bottom surface part 2 and configured to hold the medical containers 50, wherein each of the container holding convex parts 4 has a tapered shape that is thin on the upper end side thereof, the plurality of the container holding convex parts 4 are configured to a lattice arrangement on the bottom surface part 2, and simultaneously four of the container holding convex parts 4 are integrated, thereby a container housing part 6 corresponding to one of the medical containers is formed, and the medical containers 50 are configured to be brought into contact with any point from the upper end to the lower end of the four convex parts 4 so as to be held.

Abstract: The present invention provides a medical container: that is configured of an upper member and a lower member; that can be molded by injection molding; that has an excellent dimensional accuracy; and in addition to these, that is capable of effectively preventing the trouble that a molten resin for joining the upper member and the lower member enters the container. The present invention is a bottomed tubular medical container 1 made of a resin and continuously configured of a neck 12, a shoulder 14, and a body 16.

Abstract: Disclosed are a piston for a micro-volume syringe and a plunger. The micro-volume syringe has a syringe barrel with a space defined in it. The piston is slidable on and along a wall of the space. A leading member to be arranged on a side where the piston comes into contact with a solution filled in the space and a trailing member to be arranged on a side where a plunger rod is to be connected, the latter side being opposite to a solution side of the leading member, have been integrated with each other. The trailing member has a higher hardness than the leading member. With the micro-volume syringe in which a drug solution can be filled in a very small quantity, the piston makes it possible to perform smooth drawing and ejection of the drug solution without leakage. Even if the small piston connected to a tip of the plunger rod is operated in a direction that the piston is to be pulled out of the syringe, the plunger rod does not slip off from the piston accidentally.

Abstract: A medical syringe, having a syringe barrel, a piston, a plunger rod, and a plunger rod holder, wherein a barrel main body of the syringe barrel is formed to have a small inner diameter part and a large inner diameter part, the piston is formed such that the circular part is comprised of an elastic material and has an outer diameter larger than the inner diameter of the small inner diameter part of the barrel main body so that the outer periphery of the circular part can be brought into contact with the inner peripheral surface of the small inner diameter part by pressurizing, and the piston can be held in the large inner diameter part of the barrel main body in a state of being freely fitted thereto.

Abstract: A container for receiving or storing or carrying pistons for injectors, the container having a base plate and hollow cylindrical piston storage parts (the container being hereafter referred to as a piston nest). Each of the hollow cylindrical piston receiving parts is formed either by making it vertically penetrate through the basic plate, with one side of the base plate functioning as one opening end, and project from the other side or by making it vertically penetrate through the base plate and project from both sides of the base plate. Preferably, each piston receiving part has a swelled part where a part of the inner peripheral wall surface of the piston receiving part is swelled inward. The pistons for injectors are received in the piston receiving parts.

Abstract: Disclosed is a plunger rod for a syringe. The plunger rod is useful for sliding a piston within a syringe barrel. The plunger rod is characterized in that it is colored in part or in whole. The syringe is also disclosed. According to such plunger rods, even plural syringes of exactly the same external appearance and configuration can be applied with features that make it possible to readily and visually identify them by simply taking a glance at their appearances without needing a measure such as applying indication members such as labels on them. Further, the use of such plunger rods makes it possible to provide syringes of significantly enhanced visual identifiability without impairing high-level quality, functions, sanitariness and safety required for the syringes.

Abstract: A plastic-made cap for a vial having a lip, the cap being useful as a separation-preventing cap for a plug that seals up an opening of the vial, includes a top wall portion having an outer circumference and centrally defining an opening, and a cylindrical skirt portion extending downwardly from the outer circumference of the top wall portion and being open at its lower end. The skirt portion has an inner diameter (a) greater than an outer diameter (b) of the lip of the vial. The skirt portion is provided on its inner wall with plural ribs formed in a direction perpendicular to the top wall portion. The plural ribs are arranged in pairs at equal angular intervals between the respective pairs of ribs. Further, engagement claws are arranged between the respective pairs of ribs such that the engagement claws can be brought into engagement with an underside of the lip of the vial.

Abstract: A medicine syringe has a syringe barrel, piston and plunger rod. The syringe barrel is provided with a cylindrical main body defining therein a chamber to be filled with a medical solution, and an injection nozzle portion formed at an end portion of the main body and defining therein a hollow bore in communication with the chamber. The chamber and hollow bore have a total capacity of not greater than 0.5 mL. The chamber and hollow bore are formed such that the piston is slidable in a range of from 20 to 100 mm and is allowed to slide liquid-tight into the hollow bore beyond the chamber.
